IMPROVEMENT lIN OZONE-MACHINES.

l Specification forming part of Letters Patent No. 173,386, dated February 15, 1876; application tiled l July 26, 1875.

To all whom it may] concemr I Beit known that-I, FREDERIoKWr-LLIAM BARTLETT, of Buffalo, in the county of Erie and State of New York, have made certain Improvements in Ozone-Machines, "of which the following is a specification:

This invention consists in the construction and arrangement of the parts by which ozonel edge view5-andFig. 5, a sidel view ot' the phosphorus sticks.

A is a hollow glass vessel or base, having its inner face or sides formed into a series of semicircular cavities or half-tubes, a, a, and withl indentations orlsockets b inthe center of each in the bottom. B is an inner cylinder or plunger, also of glass, having corresponding semicircular cavities c c formed on the outside,l

which, when the plunger is in position, (inside the outer vessel A,) will form (in' conjunction 4 with thev other parts au) a series `ot` tubes aro'und the intcriorof the vessel, as more fully shown in Fig. 2. This-vessel A comprises the generating-chamber. The plunger B is made hollow with a closedbottom, and will be raised or lowered by a cord, d, and pulley, or any suitable means, for the purpose to be presently explained. The bottoms of the tubes a c have the sockets b to receive the phosphorus sticks e. These will stand up about twothirds of the length ot eachfwholetube t c, as shown in. Fig. 1. There being a separate tube for each .stick makes a complete separation of all, and

renders it impossible for anysticks to comI municate with or ignite each other. The space allowed in each tube above each stick of phosphorus isA very important, as ozone is first generated therein in a crude state, just enough air filling the space to get a combustion from the phosphorus.

The tubes will be from one to two inches in diameter, according to the size of the machine.

The size is also important, as the ozone -is found to generate naturally and completely in tubes of small diameter, and having a chamber from two to four inches above the phosphorus.

Inv connection with these tubes my construction of the phosphorus sticks is also important.

They are made Hat and thin, being from oneeighth (13;) to onequarter of an inch in thickness,=and one inch in width, according to the size ot' the machine, and the upper part or combustion-point iiattened'or sharpened, thus giving the best'oxidizingfpoint, and making them less likely to melt or ilash,77 as there is no accumulation ot'v heat centrally in the stick. The length is graduated to the height of the generating-tubes. In this shape the combustion isbetter and more even, and great economy in the use ot' the phosphorus is obtained. The object ot' raising and 'lowering the plunger or inner cylinder B is to regulate the height of water around the phosphorus sticks, and

"thus graduate the combustion. As the phosphorus burns down the plunger and connected tubes are gradually raised, so as to keep about the same length of stick above the water.

`There will be a sufficient quantity ot' water used to cover the phosphorus sticks when the plunger is ventirely lowered, and when raised the'water will, of course, stand'at a lower level,

and thus expose the phosphorus sticks. By this simple arrangement any length off stick desired may be exposed for quick'or slow combustion, and the machine may be left for days to run itself, the only attention required being to graduate the water by raising or lowering the plunger.

Above the glass generating-chamber or base A is arranged an ozone-chamber, C, the walls being formed o t' two thicknesses of wire-cloth,

' the inner onef being ot' much finer Wire than the outer one g,- and haviiig between the two, and surrounding-the entire chamber 0 a cotton' or linen cloth, It, or other porous fabric, paper, or cotton, and which is first treated with, or saturated in, an alkali or other chemicals, in such a manner as to .retain it in the tibers of the stuff, so that the fumes rising from the oxidizing phosphorus will be caught therein, the acids and other impurities retained or neutralizedby the chemicals having an affinity therefor, and the ozone escaping throughinto the room. This statement of the delivery ot the ozone from these vertical walls is based upon the fact that its specific gravity is greater than that of the atmosphere, and that when passing from the chamber C by its own inclination it will naturally do so from the'middle and lower part of the cylinder in preference to the upper part. All the air necessary to the combustion of the phosphorusvalso finds its Way in through these walls, and no other arrangement for air ingress is made. This chamber G thus constructed is one ot' the main come separated from the ozone. In thedomev they have a cloud-like appearance, but when the ozone filters thl ough the sides of the .clzazn-r berG it cannot be detected by the eye, b'ut its presence is Very sensibly observed in theroom.

The single tubes a c separating eachjindividual stick of' phosphorus are .also a Verylim-` portant feature of my invention, as,.,.befor,ev

stated. Their arrangement around theperiphf.

ery of the plunger, or on the inside of the'glass.

case or generating-chamber A, is also important, as, by thus placing them, the action of theI phosphorus and the height of the water can be seen andadjusted without removing the parts.y These tubes, as well as the base or vessel A, plunger B, and dome D, will be coustructed of glass, as being non-corrosive as well as transparent.

The plunger B- is made hollow, so as to regulate the temperature ofthe Water used in the vessel A, either by introducing therein ice to cool'the Water surrounding the phosphorus, or hot water, Ste., to raise the temperature.

The prepared porous stuffs are renewed as oftenl asalecessary, and the adja-cent parts are maderemovable for that purpose.

I claim- 1. In an ozone-machine, the'combiuation of the hollow vessel or base A of glass, having aser-ies of semicircular cavities, a a, on the inside and sockets b inthe bottom, With the plunger B, having a similar series of cavities, c, onthe outside, and an adjusting mechanism for the purpose lot' adjusting the height of the Watervaroundy the. phosphorus and regulating its combustion,substantially as described.

2. In an ozone-generator, the walls f and g ot-` wire-` gauze, With an interposed layer ot' fibrous material saturated with alkaline solu- F. W. BARTLETT.
